Was Galileo Really Tortured by the Church?

The story is almost too good: a brilliant astronomer is dragged before the Inquisition, forced to deny that the Earth moves, and mutters defiantly under his breath as he leaves. It has become a founding legend of the supposed war between science and religion. The facts are messier, and more interesting.

The man and his powerful friends

Galileo was no outsider. He was a celebrated court philosopher in Florence and counted Cardinal Maffeo Barberini among his admirers. When Barberini became Pope Urban VIII in 1623, Galileo hoped for support. In 1616 the Church had already warned him not to hold or defend the Copernican system as true, but allowed him to discuss it as a hypothesis.

The book that caused the trouble

In 1632 Galileo published the Dialogue Concerning the Two Chief World Systems, a lively conversation between three characters. The defender of the old view, named Simplicio, seemed to many readers a fool, and some believed he mocked the Pope’s own arguments. Urban felt betrayed, and personal anger mixed with theological concern.

The trial and its myths

In 1633 Galileo was tried, found “vehemently suspect of heresy,” and made to recant. The sentence was house arrest, which he served in comfort at his villa near Florence until his death in 1642. He was shown the instruments of torture, and threatened under the formula of “rigorous examination,” but there is no evidence he was tortured. The line “eppur si muove” is first recorded in the eighteenth century. In 1992 Pope John Paul II acknowledged that the Church had erred.

Editorial assessment

The legend is attractive because it turns an intricate dispute, involving politics, patronage, theology and ego, into a morality tale. The real episode suggests that institutions defend authority as much as belief, and that individuals matter. Galileo’s mistakes included the way he argued as well as what he argued. Both sides were more human than the legend allows.
